The Universal Asynchronous Receiver/Transmitter (UART) is a full-duplex 
communication channel capable of handling asynchronous data transfers. The two UARTs
use a single 8-bit data mode with selectable parity.
The UART interface when enabled uses the GPIO pins P07 for the UART transmit and
P32 for the UART receive.
The features of the UART include:
•
•
